MANUFACTURE OF TILE.

Specification of Letters Patent.

Application filed January 23, 1909. Serial No. 473,841.

To all it may concern:

Be it known that I, ALBERT A. PAULY, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented or discovered new and useful Improvements in Manufacture of Tile, of wh1ch the following is a specification.

My invention relates to the continuous- 1 manufacture of concrete blocks, tiles, etc.,

that is, to the apparatus and method whereby all of the steps of manufacture are being simultaneously carried on. i

In one'part of the apparatus the cement is being continuously mixed and fed to thecarriers; another part containing a number of molds receives the cement from .the car: riers and molds it into the required forms; another part transfers the molded forms to carriers which. are fed in succession into the fi'ont ofa drying or curing kiln, the cured articles being returns the empty carriers to a return track, on which they are brought back to the front of the kiln to be refilled from the molds.

Referring to the drawings, which are diagrammatic merely, Figure 1 is a plan, partly in horizontal section, showing the preferred general arrangement of the componentelements; Figs. 2 and 3, similar longitudinal sections, showing different stages of the manufacture; and Fig. 4, a transverse Vertical section through the drying kiln on the line 4-4, Fig. 1.

In the description following it is to be understood that the drawings are merely conventional signs to indicate the presence.

of certain features generally and of certain sequence of steps.

Tlheapparatus may be quite different from that shown without departing from the spirit of my invention.

On the drawings, 1 designates the walls of a building or inclosurc in which the apparatus'may be placed.

2 is a storage bin having the compartment for crushed stone and the compartment 4 for sand and cement.

5 is the delivery spout which may be the upper end of an elevator, (i being a hinged section whereby the different components of the concrete may be diverted to the proper compartment of the bin.

7 and S are measuring boxes beneath the I pushed out of the rear of the kiln as soon as they are ready; another part compartments 3 and 4, into which boxes the materials in the bin may be discharged as desired by opening the gates 9. The boxes 7 and 8 dischar e their contents'into the rear end of the mixin tank 10, in which there is a rotary spiral eeding and mixing device 11, the materials being by the spiral thoroughly mixed as they are fed toward the open end of the tank. The contents of the tank 10 are discharged into the concrete storage tank 12, having its center below the delivery end of the tank 10. In the tank 12 there are two spiral mixers and conveyers 11 arranged to move the concrete from the ends toward the center, at which place is the delivery spent 13. I arrange preferably in a line near the spout 13, a series of molds 14, over which lie the trolley tracks 15 and 16, diverging from beneath the spout 13.

17 represents a drier, or curing oven or house, having a numb r of parallel chambers.

Patented July 19, 1 910. i

At the ends of the-drier and over the drop-ends of the tracks are the drums 23 and 24:, provided with the chains 25 and 26, the

chains being attachable to the carriers 21 so that the latter may be raised or lowered as required. In each chamber 18 is a track 27 extending longitudinally through the same but beneath the. tracks 19. The tracks 27 have their ends rigid and extended somewhat beyond the ends ofthe tracks 19. The

of nearer the molds 14.

28 represents the doors by which the ends of the drier may be closed.

- 29 is a steam pipe atthe bottom of each chamber 18. These pipes have openings to admit'steam to the chambers and receive their supply of steam from the steam main 30.

31 a steam main. supplied from any source through the pipe 32 andsupplies steam for heating the molds 14 in a well known manner through the branch pipes end of the tracks 27 is lower at the end there- 34:.are pipes conveying steam from the .molds to the main 30. T e arrangement of the steam pipes may be as desired, as I have not attempted to do more than to show their presence. On the trolleys 15 and 16 are the cars which receive the concrete from the spout 13 and convey it along the tracks 15 or 16 to positions over the molds 14, into which they discharge their contents.

The constituents of'the concrete are mixed in the tank 10 and conveyed to the tank 12 in which the concrete is still further a itated and from which the concrete is discharged into the cars 35. The cars are run along the trolley tracks 15 and 16 to positions over the molds 14 and discharge their contents into them. After the molded articles have become sufficiently set, which is hastened in a well known manner by the steam passing from the branch pipes 33, they are placed on the cars or carriers 21, which are lifted by the chains 25 with the wheels at the level of the tracks 19, whereupon the forward ends of the tracks are raised as shown in the upper track in Fig. 3, and the chains 25 detached from the cars. The cars 21 are successively pushed into the oven.-

Each car after the first on any track pushes the preceding cars along the track 18, causing the cars to move step by step. All of the tracks, or so many as shall be necessary, are thus supplied with cars. are 'keptclosed except when cars are entering or leaving the chambers and steam is constantly supplied through the pipes 29 for the purpose of hastening the curing process. The cars should consume such time in their travel through the oven'as will cause the The doors 28 articles to be cured or seasoned to the required degree. With known temperature of the steam and composition of the concrete, 1t

will be possible to make the process contincharged cars are connected to the chains 26 and then lowered to the tracks 27, the dropends 20 which are in the Way being first swung down as shown in Fig. 3. After the cars have reached the tracks 27, the chains 26 are detached therefrom, whereupon the cars run by gravity back to the" front end of the oven to positions near the molds where they can be reloaded with freshly molded tiles.

I claim- In the manufacture of cementitious articles, a curing oven, two tracks therein one over the other, the upper track having an extensible end, a hoisting device over the extensible end of said track, and a car adapted to be detachably connected to said hoist and to move on saidtrack and its extensibleend, the said extensible end of the track being adapted to be withdrawn to permit the hoist with a car thereon to pass from one track to the other.

Signed at Youngstown, 0., this 19" day of January, 1909.
